To all {Lv/wm, 'it may concern:

' Be it known that I, CHARLES AUGUST HUL- 'rIN, 'a citizen of the UnitedStates, and re' siding city of Seattle, county of/Kin'g'Vand State ofWashington, have invented a new and usefulDough Divider and Scaler, ofwhich the following is alclear and concise specification.

My inventionrelates primarily to a machine for dividing dough intopieces of a prefdeterm'ined weight without substantially compressing thedough lthus divided; a machine with great latitude in cutting pieces ofdough into from the smallest sizes 'to the largest loaves used in abakery; secondarily Ato aii'ord a' means for preventing the dough deviceas illustrated in the accompanying drawings, and hereinafter more `fullyset forth.

' the dough while: being actuating. gears.

I have provided a durable machine with an extremely great capacity.

The objects of my invention are to provide a dough divider which willnot' compress divided, to afford a means for cutting pieces ofsubstantially uniform size; to change the size being cut at a minimumtime 'and labor; to prevent dough from sticking to the rolls andframe-work. I accomplish this, as well as minor objects with theconstruction now preferred by me illustrated in lthe accompanyingdrawings, in which,

Figure 1 is a vertically transverse section of my entire device. Fig. 2is a fragmentary side elevation showing the driving and knife ig. 3 isafragmentary elevation and section showing the rapid change mechanism ofsaid knife actuating gears. Figli is an elevationv of a knife. Fig. 5 isa transverse section of a cutter hood and cutter bearings. Fig. 6 is apartial section and elevation of the cutters.

at No. 229` North Broadway, in the the dough while Fig. 7 is a plan viewof one of the nozzles of .my device. Fig.; 8 is a side elevation'of myentire device.

Similar numerals refer to the several parts throughout the severalviewsof the accom panying drawings.

I have provided two side frame pieces 1 and 2 provided with aperturesadapted to journal the top station ar-y feed Aroll shafting 3; themiddle station- 4 ary feed roll shafting 4, and the lower stationaryfeed roll shafting 5, the drive shafting .6, which is provided with thegears 7 and 8 rigidly secured thereto. Said gear 8 bea frame workcomprising ing adapted'to intermesh with the gearv 9,

`which is supported by a stud 10, and rigidly secured'to a .pinion 11,which intermeshes with Vthe gear 12, whichis rigidly secured to saidlower stationary feed roll shaft 5, which is adapted to drive the lowerfeed roll 6 having a flange 7 substantially flush with the inner surfaceof said side frame piece 1. Said lower feed roll shaft 5 is alsoprovided at its-opposite endwith the gears 13 and 14; said gear 13 beingadapted tointermesh with the. gear 15, which is rigidly secured to thecutter shaft 16, which is j ournaled .in the cutter hood 17, which isadapted to protect the cutters 18, which are rigidly secured to thevcutter shaft 16 by means of collars 19 and the nut 20. Itis obviousthat said cutters- 18v may be of any number by placing collars 19 ofdifferent widths there-between. Thus the cutter as 18 may be removed, aswell as the collars 19, and 19 land a collar of substantially the widthof both the said collars 19 and 19 as well as the thickness of 'saidcutter 18 added thereto, and in a similar manner other combinations ofcutters may be used. Said cutter hood 17 and the cutter shaft 16, aswell as said gear 15, may be lremoved and another cutter hood as 17 andparts connected thereto may be substituted by loosenthehood screw 21 bymeans of a hand wheel 22, rigidly secured thereto, said hood screw beingthreaded adapted to t the bail 23, being mounted on the pivots 132.

The aforesaid gear 14 is adapted to intermesh with the idler gear 25,which is supported by a stud 26, rigidly secured to said side and framepiece 1 and adapted to intermesh with the gear 27, which is rigidlysecured to said middle stationary feed roll shaft i, said gear 27 beingadapted to iultermesh with thdidler'gear 28, which is suptionaryfeedroll shaft which is supported by gear 35 being adapted to intermeshwith the gear 37, which is rigidly secured to the top movable feed rollshaft 38, which may be adj top stationary feed roll shaft and isportedby cured to `said side-frame y gea-rs 56 secured to 28 beingadapted to intermesh with the gear 30, which is rigidly secured to saidtop sta- 3; said gear- 30 is adapted to intermesh with the' idler gear31,

secured 'tothe' link 33 and the link 34; said idler gear'31 is adaptedto intermesh with vidler gear 35, which is vJou-rnaled on. the pin 36,which'is secured to said link34, the idler justed relative to saidftopstationary feed roll shaft`3 by 'means of the screws 39 operated by thebevel gears 40 and 41. Said screws 39 are threaded and adapted to t thebearing supports 42, said bevel, gears 40'- being rigidly secured tosaid screws 39, and said bevel gears 41-y being rigidly secured to ahand wheel shaftU43, which is secured to the. hand wheel 44. It is thusobvious that the movable top feed roll 45 may b e raised and loweredrelative to the top stationary feed roll 46, which is rigidly secured toVsaid provided with a flange 47.'- Saidgear 37' is adapted to intermeshwith an idler gear 48 which is supported by means of a pin 49 and link50, which' are' provided with al slot 51 to fit the lower movable feedrol-l shaft 52, thus allowing an independent movement for adjustment ofsaid shaft 38 and said shaft 52, and itis obvio'us that said shaft 38may be raisedor lowered relative to said shaft 3 and said gear 30 fromwhich said sjear 37, secured to said gear. 38, is driver as said links33 allowsaid pin 32 to swin,y conceni movable feed roll 61, which, issecured tosaid shaft 52; said feed roll 61 is adapted to fit the sideframesl 1 and 2 on its ends, as Well as between the anges 62'of. .themiddle feed roll 63Which is. secured to said shaft 4.

Thus the dough is fed from a hopper 64 whichis pivotally connected tofeed said dough at diiferent speeds by means .65 adapted to engage,teeth 66 provided on said Si 'and i 45, theends ,65.

e `frames 1 and 2 to the top rolls 46 ofV which snugly fit the ianges47: of sald roll 46, thus said flanges means 'off the stud 29,rigidly-sa.` piece 1; said gear" the pin 32 rotatably` intermesh withwith the hand wheel 58.'

of pawls' form moving for the remainder of. its side walls the innersides of a chute 67 whichhas surfaces of said side framepieces '1 and 2,

and for its bottom the rollsf46, 63 44and a' bottom roll 68, which'issecured tosaidfsha'ft- 69, 7 0 aha7-.1, the; upper ends of` which areprovided with 5, as well as chute pieces Scrapers 72, 73 and"74, whichare ada ted to remove any.. dourh which may Stic to said rolls46, 63an68,; the lower'end of said chute pieces 69 and 70 bein held slightlyaway vfrom saidrolls 63fan 68' to force slots 75 and 76 to permit flourfrom the nozzles 77 and 78 to enter therethrough to prevent dough fromsticking lto said rolls 63 and 68, said roll 46 being supplied withflour through theslot 79 formed between the vlower end of said hopper 64and said roll 46 and by the nozzle S0, said movable feed rolls 45 and 61are supplied "with flour from nozzle 83. To scrape dough which may havestuck on said movable rolls 45 and 61 I have scrapers 84 and A 85swingingly mounted on saidy shafts 43 and 57 and held in contact withsaid rolls by means of levers 86 and 87 and weights 88 and 89 securedthereto, and to remove stick on said cutters 18 A scraper ,90 secured tosaid cutter hood 17. After the dough has passed through the .chute androlls and has been cut longitudinally by said cutters 18 a rotatablynounted knife'91 cuts the dough transversely',and

dough which may I have provided a the pieces thus cut gravitate overthe' apron.

92 onto the conveyer belt 93, which is driven by a pulley 94 which isshaft 6. To change the 'speed of said knife M0' secured to said 91 andto drive said knife I have provided loosely mounted gears 95 and 96adapted to said gears 7 and 8, which are also secured to said shaft 6Vand driven thereby. It will be 'seen that as-said gear, 95

intermeshes with a smaller gear as 7 and the gear 96 intermeshes with arelatively larger gear as 8 that by driving the shaft 97 bysaid'l gear95 that said shaft 97 and parts driven thereby willtravel slower thanwhen said gear 96 is made to drive said shaft 97, and

los

by the lconstruction illustrated inl Fig. .3 -of l the accompanyingdrawings a slidably mounted feather to yieldingly travel from a in saidgear 95 to a feather I have provided feather way 99 way 100 in said key98 adapted gear 96 by overcoming the spring 101, which 1s secured to therod 102, said key 98 is also pivotally secured to said rod 102, which-isguided by `an aperture in the cap 103 and the bottom of the keyway 104'and is operated by a knob 105 secured to the end thereof. The oppositeend of said shaft 97 is provided with a bevel gear 106 intermeshing withthe bevel gear 107, which is secured -to the shaft 108 having said-knife 91 secured thereto, which is driven by the dowels 109, whichareproportioned tobreak off when foreign matter venting said knife frombeing broken. .i

have provided a cover 11() to prevent ac` cidents, having a connection111 to keep said knife 91 supplied with fiour.

The nozzles 78, 77 80, 81, 82, 83 and connection 111 are connected withthe discharge pipe 112 of a fan 113, which is driven by a belt 111running on the pulley 115, secured to the shaft 116 of said fan 113, aswell as by the pulley 117 secured to th'e shaft 118, which is providedwith a pinion 119 adapted to intermesh with said gear 9. I have'provideda sifter ,120 having a slot 121'anda slot valve 122 operated by theshaker 124 which is oscillated by the lever 125 and link 126, which issecured to the crank 127 driven by said gear 12, tb regulate the feedof'iiour into the suction pipe 128 o'f said 'fan -113. Thus it isobvious that the required amount of flour may be delivered to therolls,cutters and knife of my device through the connections to said fan`113and through the several nozzles which are preferably provided with anadjustable slot 129 regulated by'shiftingthe sleeve 130 shown in Fig. 7of the accompanying drawings. .It is cbvious that by changing therelative speed 0f the cutters,.knife and rolls that the dough suppliedto my out being compressed, and may be shredded if desired, and that Iam enabled to cut pieces of dough of sizes greatly varying in weight,and by the use of the Scrapers and flour supplying means I am able tohandle-'dough which is wet and sticky before being supplied to mydevice. the cutter shaft 16 being journal'ed in bearings 131 secured tosaid hood 17 that said hoed and said cutter and parts attached theretomay be replaced and a shaft as 16 with a new combination of cutters as18 may be substituted by looseningv said hood screw 21 and swinging saidbail 23 clear, which is facilitated by the pivotal connection 132 beingof greater radial distance from the end of said screw 21 than the radiusof said hood. I thus adord a rapid means for changing said cutters.

I do not wish to be limited to the specific construction set forth andillustrated in the accompanying drawings, but wish the liberty to departfrom such details as are within the scope of my patent.

Having thus described my invention what I claim as new, and desire tosecure by Let ters Patent in the Patent Office of the United States,isz.
